A Modelling and Simulation of a Sensorless Control of Five-phase PMSM Drives using Multi-dimension Space Vector Modulation
Abstract: This paper
introduces a new method to track the saturation saliency for position
measurement of a five-phase PMSM motor fed by a five-phase inverter through
measuring the dynamic current response of the motor line currents due to the
IGBT switching actions. The new method uses only the fundamental PWM waveform
obtained using the multi-phase space vector pulse width modulation (i.e there
is no modification to the operation of the five-phase inverter) similar to the
fundamental PWM method proposed for a three-leg inverter. Simulation results
are provided to verify the effectiveness of the proposed strategy for saliency
tracking of a five-phase PMSM motor driven by five-phase inverter over a wide
speed ranges under different load conditions.
